Lung
Bladder 
GI tract 
Sweat glands
Sex organs
Blood vessels

Question 12

How does the eye respond to cholinergic receptor activation

Answer 12

• contraction of ciliary muscle focuses the lens for near vision; Contraction of the iris sphincter muscle causes miosis (decreased pupil diameter)

Answer 15

Bladder
